HUGH WILLIAMSON KELLY, OF PROVIDENCEQRHODE ISLAND, ASSIGNOR OF ONE-HALFTO, AUBREY LOVE,- OF RIDGEWOOD, 1 TEW JERSEY.

rnooisiss or MAK NG TRACK-TORPEDOES.

T all whom it may concern:

Be it known that I, HUGH "VILLIAMSON KEILY, a citizen of the UnitedStates, and

a resident of Providence, Rho'de Island,

have invented Improved Processes of MakingTrack-Torpedoes, of which'thefollowing is a specification.

"My invention relates to track torpedoes of thetype set forth in myPatent Number 1,248,670, dated December 4, 1917, and the object-of mypresent invention is to form a molded torpedo of rubber or rubber-comtaining material with the explosive charge l positioned within the same;sai'd torpedo,

or the molded'shell comprising the same,

having integral lugs for gripping the head of a rail in order that itmay be properly positioned with respect to said rail.

According to my present invention, the

detonating or explosive material, whether contained within asuitable'envelop or not, as may be necessary or desirable, is introducedinto a suitable mold with the desiredamount of rubber orrubber-containingiinateri'al properly positioned with respect to thesame, and then the mold with the'contained material is'subjectedto'hea't and pressure so as to produce an integral continuous-walledcontainer or shell having 7 80 the integral lu'gs'whereby it may besecured to? the head of. a rail, and inclosing such detonating charge.

"These and other features of my invention are more fully describedhereinafter, 'i 35 referencebeing had to the accompanying drawings, inwhich:

Figure1, represents one form of molded torpedo'jof the type to Which myinvention relates positioned upon a rail head.

to Fig. 4, showing forms of molds in which torpedoes of the shape ortype illustrated in Figs. 6 and 7, may be formed.

Figs. 10 and 11, are cross'sectiona'l views similar to Fig. 5, of themolds" shown in Figs. 8 and 9, and

Figs. 12, 13, 14, 15,16 and 17, illustrate other modifications withinthe scope of my invention.

The shell 1 of the torpedo illustrated in Figs. 1 and 2 at 869., may beathin-Walled structure, with the ends beveled as at 2, and the sidesbeveled as indicated at 3; the base 4 being shaped to conform to thesurface of the rail-head, with rail-engaging lugs 5 continuous with thewalls of the structure.

In forming or making this structure, the charge is disposed within themold in which the shell is shaped, as shown in Fig. 4, in which thecharge 6 is represented as inclosed within a suitable envelop 7, and therubber or other'material'to formthe shell of the structure is placedwithin such mold in the space indicated at 8. In some instancesltheenvelop 7 may be omitted. The mold with its inclosures thus prepared isthen subjected to the necessary heat and pressure whereby acontinuous-Walled shell inclosing the charge and having therailengagin'glngs 5 is formed as a single integral and homogeneousstructure, as illustrated in the several views of the drawing". Ifdesired, the charge may be prei'nolded or shaped in the form of a cake'orblock, and in such instance the envelop or container 7 may beomitted.

In the form of torpedo'shown in Fig. 6,

a broad detonating-chargecontainer 1 is around which thesections ofrubber or rubher-containing material are placed.

In the form of-torpedo shownin Fig. 7, a roundedcentral chamber 1 isprovided for the detonating charge; said chamber sur mounting the stripor band 'formiiigthe base 4", and the ends of said base are pref erablystiffened by integral bracing members 9. Figs. 9 and 11, show the mannerin which this form of torpedo is made and,

as in the other structures referred to, the

detonating charge may be either a premolded block, or contained within asuitable envelop before insertion in the mold.

meansto assist in retaining the same upon the head of a rail.

In some instance it may be desirable to provide the torpedoes withstraps '5, long enough to extend under the head of the rail, and in Fig.12, I have shown a sectional view of a torpedo of this type. Such formof torpedo may be molded in a mold of the character illustratedgenerally in Figs. 4 and 5; provision being made for the formation ofthe elongated straps with their ends to underliethe rail heads, and inFig. 13, I have shown a mold of this type.

It will be understood, of course, that forms of these molded torpedoesmay be, if desired, made in'more'than one piece, and in Fig. 14, I haveshown a type of a two-part structure in which the parts 11 and 12, areseparately molded and the whole then assembled after the detonatingmaterial has been set in place. In this form of the torpedo, the member11 will have rail-engaging lugs 5 of substantially the same type asthose illustrated in Figs. 1, 2 and 3; the same being integrallyconnected with said member 11 which has lugs'or ears 13 whereby it mayengage the walls ing section 12. This molded, and the same ceive thecharge 6 of detonating material which will be confined in place uponapplication to the lug-carrying base. If desired,

of the charge-containsection may also be will be hollow to rea cementingbody of some nature may be- .employed to connect the parts together or'tohermetically seal them and thereby protect the detonating materialfrom the ingress of dampness or moisture.

In Fig. 16, I have shown a sectional viewof another form of torpedowhich may comprise a tubular member of compressible material. In thisform of structure, I may provide a tubular device 15 of rubber, or ofany suitable friction fabric having a waterproof wall, and whenfinished, its ends will be open for the reception of independent lugs16,. which may be previously molded and which may be attached to theends of said tubular member in any suitable manner.

For instance, said lugs may be sewed to the ends of the tubular memberat 17.

In referring to the shell of the torpedo as made of rubber,

it will be understood, of

course, that what is meant is a rubber-con taining material, thequantity; of rubber in as indicated which may be relatively smalli' Theobject,

is to provide a relatively"flexibleistructure suitable for the purposeand one that will be non-flying and therefore not dangerous by reason ofany onation of the charge.

The connection between the lugs and the base of the shell or containerin all forms of flying parts under the det- V my improved structure arepreferably of a relatively better grade of material than that comprisingthe container, so" as to insure the desired resiliency and at the sametime the required tension upon the lugs 5 when they are placed in arail-engaging position.

As this application possesses matter in common with an application filedby me May 27, l916,..Serial Number 100,259, it. is v to be treated as acontinuation of said prior application as far as the common subjectmatter is concerned. .I claim: V V f I 1.
